webapp-deployment-status-api

This API provides status information about webapp deployment requests and a mechanism for upload encrypted configuration files used by those requests.

Build and Run

yarn
yarn build
yarn start

Configuration

Keys

Configuration files are encrypted prior to being uploaded using an RSA publicKey specified in the WebappDeployer record. On upload, the configuration is temporarily decrypted for validation, but stored in its encrypted format.

To create and export a key in the necessary format use:

# Create a key
gpg --batch --passphrase "SECRET" --quick-generate-key webapp-deployer-api.my.domain.com default default never

# Export the public key
gpg --export webapp-deployer-api.my.domain.com > webapp-deployer-api.my.domain.com.pgp.pub

# Export the private key
gpg --export-secret-keys webapp-deployer-api.my.domain.com > webapp-deployer-api.my.domain.com.pgp.key

Create the Deployer Record

Every webapp deployer should have WebappDeployer record in the registry which looks something like:

record:
  type: WebappDeployer
  version: 1.0.0
  name: webapp-deployer-api.my.domain.com
  apiUrl: https://webapp-deployer-api.my.domain.com
  minimumPayment: 100alnt
  paymentAddress: laconic1clpc8smrhx5k25zmk3vwna8kddxrsem7a1jlry
  publicKey: mQGNBGbJUk0BDAC3j3CiaVtoEf1jrgtsjJnTA5u1a3BExP72mv0eE8y84TgY5rVcf ...

This record can most easily be created using laconic-so publish-deployer-to-registry.

laconic-so publish-deployer-to-registry \
  --laconic-config ~/.laconic/registry.yml \
  --api-url https://webapp-deployer-api.my.domain.com
  --public-key-file webapp-deployer-api.my.domain.com.pgp.pub \
  --lrn lrn://laconic/deployers/webapp-deployer-api.my.domain.com  \
  --min-required-payment 100

This will create the record in the proper format and assign its LRN.

Publish Deployment Auction

Users can optionally create an auction for app deployment with desired number of providers and max price they are willing to pay for a deployment:

laconic-so publish-deployment-auction \
  --laconic-config ./config.yml \
  --app lrn://deepstack/applications/pwa-test-13 \
  --commits-duration 3600 \
  --reveals-duration 3600 \
  --commit-fee 10000 \
  --reveal-fee 10000 \
  --max-price 5000000 \
  --num-providers 3

This will create a provider auction with given params and publish a deployment auction record.

Request Deployment

Users can now request deployment using the LRN of the deployer. This will allow them to:

1. Discover the API URL for config uploads.
2. Obtain the public key for encrypting config.
3. See the minimum required payment.

The request can be made using laconic-so request-webapp-deployment. This will handle encrypting and uploading the config automatically, as well as making a payment (if necessary).

laconic-so request-webapp-deployment \
  --laconic-config ~/.laconic/registry.yml \
  --deployer lrn://laconic/deployers/webapp-deployer-api.my.domain.com \
  --app lrn://cerc-io/applications/webapp-hello-world@0.1.3 \
  --env-file hello.env \
  --make-payment auto

Alternatively, users can also use a deployment auction they created instead of making the payment to any specific deployer directly:

laconic-so request-webapp-deployment \
  --laconic-config ~/.laconic/registry.yml \
  --app lrn://cerc-io/applications/webapp-hello-world@0.1.3 \
  --env-file hello.env \
  --auction-id 4c9701c22651e143202e991056b6e7649853acc5bc0e97e3a98e09c9f3355909

Similar to requests with payments, the config is automatically encrypted and uploaded to all the deployers who have won the auction.
